How to use

Make sure to check out examples for more details.

Installation

Add the following line to pubspec.yaml:

dependencies:
  calendar_date_picker2: ^0.4.9

Basic setup

The complete example is available here.

CalendarDatePicker2 requires you to provide config and value:

• config contains the configurations for your calendar setup and UI.
• value is initial values passed into your calendar picker, value must be a List.

The minimum working sample

CalendarDatePicker2(
  config: CalendarDatePicker2Config(),
  value: _dates,
  onValueChanged: (dates) => _dates = dates,
);

Single Date Picker Configuration

During the initialization of CalendarDatePicker2Config the calendarType of the config instance will by default set to CalendarDatePicker2Type.single, so you don't have to set the calendar type specifically.

Multi Date Picker Configuration

In order to use multi mode date picker, you will need to set the calendarType of config to CalendarDatePicker2Type.multi:

CalendarDatePicker2(
  config: CalendarDatePicker2Config(
      calendarType: CalendarDatePicker2Type.multi,
  ),
  value: _dates,
  onValueChanged: (dates) => _dates = dates,
);

Range Date Picker Configuration

In order to use range mode date picker, you will need to set the calendarType of config to CalendarDatePicker2Type.range:

CalendarDatePicker2(
  config: CalendarDatePicker2Config(
      calendarType: CalendarDatePicker2Type.range,
  ),
  value: _dates,
  onValueChanged: (dates) => _dates = dates,
);

Use built-in dialog display method

This package includes built-in support to display calendar as a dialog. To use it, you will need to call showCalendarDatePicker2Dialog, which takes three required arguments: context, config, dialogSize:

...
var results = await showCalendarDatePicker2Dialog(
  context: context,
  config: CalendarDatePicker2WithActionButtonsConfig(),
  dialogSize: const Size(325, 400),
  value: _dates,
  borderRadius: BorderRadius.circular(15),
);
...

Config options

For CalendarDatePicker2Config:

In addition to the configurations above, CalendarDatePicker2WithActionButtonsConfig has 9 extra options

Custom UI

By using the configs above, you could make your own custom calendar picker as your need.

CalendarDatePicker2WithActionButtons(
  config: CalendarDatePicker2WithActionButtonsConfig(
    firstDayOfWeek: 1,
    calendarType: CalendarDatePicker2Type.range,
    selectedDayTextStyle: TextStyle(color: Colors.white, fontWeight: FontWeight.w700),
    selectedDayHighlightColor: Colors.purple[800],
    centerAlignModePicker: true,
    customModePickerIcon: SizedBox(),
    dayBuilder: _yourDayBuilder,
    yearBuilder: _yourYearBuilder,
  ),
  value: _dates,
  onValueChanged: (dates) => _dates = dates,
);

Multi-language support

This package has multi-language supports. To enable it, add your Locale into the wrapping MaterialApp:

MaterialApp(
  localizationsDelegates: GlobalMaterialLocalizations.delegates,
  supportedLocales: const [
    Locale('en', ''),
    Locale('zh', ''),
    Locale('ru', ''),
    Locale('es', ''),
    Locale('hi', ''),

  ...
